Run coverlet and reportgenerator in a macOS DevOps Pipeline

I have a C# project written in dotnet core 2.1 which I'm trying to set up an Azure Pipeline for so that I can get code coverage when running on a macOS agent (I can change to other agents, but ideally the pipeline would be system agnostic). So far I have been trying to get coverlet and reportgenerator to work together, but I keep running into problems, such as Could not find data collector 'XPlat Code Coverage'.

What I would like to happen is the code coverage is determined (which coverlet seems to be doing) and a code coverage report generated and displayed in Azure pipelines in some manner.

This is the pipeline I have so far:

pool:
  vmImage: macOS-latest

variables:
  solution: 'src/MySolution.sln'
  buildPlatform: 'Any CPU'
  buildConfiguration: 'Debug'

steps:
- task: DotNetCoreInstaller@1
  displayName: 'Use .NET Core sdk 2.2.103'
  inputs:
    version: 2.2.103

- task: DotNetCoreCLI@2
  displayName: 'Restore NuGet packages for $(solution)'
  inputs:
    command: 'restore'
    projects: '$(solution)'

- task: DotNetCoreCLI@2
  displayName: 'Build $(solution)'
  inputs:
    command: 'build'
    projects: '$(solution)'
    arguments: '-c $(buildConfiguration)'

- task: DotNetCoreCLI@2
  continueOnError: true
  inputs:
    command: custom
    custom: tool
    arguments: install -g coverlet.console
  displayName: Install Coverlet tool. This task will continue on error.

- task: DotNetCoreCLI@2
  displayName: 'Run tests for $(solution) collecting code coverage result'
  inputs:
    command: test
    projects: 'src/MySolution.SomeProject.Tests/*.csproj'
    arguments: -c $(buildConfiguration) --collect:"XPlat Code Coverage"

- script: coverlet src/MySolution.SomeProject.Tests/bin/$(buildConfiguration)/netcoreapp2.1/MySolution.SomeProject.Tests.dll --target "dotnet" --targetargs "test src/MySolution.SomeProject.Tests --no-build"
  displayName: Run Coverlet to get code coverage.

- task: DotNetCoreCLI@2
  continueOnError: true
  inputs:
    command: custom
    custom: tool
    arguments: install -g dotnet-reportgenerator-globaltool
  displayName: Install ReportGenerator tool

# This outputs Analyzing 0 classes, and an index.htm file is created, but not sure how to access it
- script: reportgenerator -reports:$(Build.SourcesDirectory)/coverage.json -targetdir:$(Build.SourcesDirectory)/coverlet/reports -reporttypes:HtmlInline_AzurePipelines
  displayName: 'Create reports.'

# Not sure what this should be
- task: PublishCodeCoverageResults@1
  displayName: 'Publish code coverage'
  inputs:
    codeCoverageTool: Cobertura
    summaryFileLocation: $(Build.SourcesDirectory)/coverlet/reports/Cobertura.xml

So I got it working. I had some how missed that you can specify the format that coverlet uses. By default it outputs coverage.json, but by giving the format as cobertura it outputs coverage.cobertura.xml. So this yaml script works:

pool:
  vmImage: macOS-latest

variables:
  solution: 'src/MySolution.sln'
  buildPlatform: 'Any CPU'
  buildConfiguration: 'Debug'

steps:

  displayName: 'Use .NET Core sdk 2.2.103'
  inputs:
    version: 2.2.103

  displayName: 'Restore NuGet packages for $(solution)'
  inputs:
    command: 'restore'
    projects: '$(solution)'

- task: DotNetCoreCLI@2
  displayName: 'Build $(solution)'
  inputs:
    command: 'build'
    projects: '$(solution)'
    arguments: '-c $(buildConfiguration)'

- task: DotNetCoreCLI@2
  displayName: 'Run tests for $(solution) collecting code coverage result'
  inputs:
    command: test
    projects: 'src/MySolution.SomeProject.Tests/*.csproj'
    arguments: -c $(buildConfiguration)

  continueOnError: true
  inputs:
    command: custom
    custom: tool
    arguments: install -g coverlet.console
  displayName: Install Coverlet tool. This task will continue on error.
